M/ArawIAT/Vafio/iey A T TO R NE Ys Patented Dec. 26, 1950 THREAD WINDING MACHINE William E. Mahoney, Pawtucket, R. I., assignor to Premier Threadycompany, a corporation of Rhode Island Application January 22, 1948, Serial No. 3,712

ferred to, the traverse for guiding the thread upon the package presses upon the package by reason of the same being mounted upon a weighted lever. The arrangement is such that as the package fills up, the portion which presses upon the package is moved further from the axis by swinging about its pivot. However,-this pressure of the traverse guide upon the package causes a tight or hard wind, making a rather hard package, and thisis true even though the weight is counted-balanced to a large extent. i

One of the objects of this invention is to provide an arrangement whereby a soft -package, or one that is not wound as tightly as heretofore, may be provided.

Another object of this invention is to guide the yarn to the package without causing the guiding beams to contact the package, so that this pressure and'contact will not cause the hard wind, where the same is undesirable.

Another object of this invention is to remove the pressure from the individual thread as it is delivered to the take-up package. I

Another object of the invention is to utilize the broad surface of the roll which controls the axial movement of the package by contact with the surface of the package and the conicalbase ,for controlling the movement of the thread guide in its desired relation to the surface of the package,

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appendedclaims.

In the accompanying drawings:

v Figure 3 is a-fragmental elevation similar to Figure 2, but illustrating some of the parts removed to better expose other parts;

Figure 4 is an elevation of the contact or follower roll which engages the surfaceof the package and also governs the axial movement of the package; and

Figure 5 is a diagrammatic view showing the thread guide spaced from the package.

In proceeding with this invention; I modify the winding machine, such as illustrated in my Patent 2,099,985 dated November 23, 1937, by conto a thread winding ma- 6 Claims. (Cl. 242-31) necting together through gears the swinging mechanism which carries the traverse guide for the thread, and the swinging mechanism which engages the surface of the package and the conical base, so that as one of these move, the other will move correspondingly with reference to the axis of the package, the arrangement being such that both will move toward the axis of the package or both will move away from the axis of the package in unison. By this arrangement, the means which urge one of these swingng parts toward the axis of the package will also urge the other one toward the axis of the package, and by this arrangement, I may mount the traverse guide at a distance spaced from the package a predetermined amount, and as the package fills up, this spacing between the surface of the package and the traverse guide will be maintained constant throughout the building of the package, and by this spacing, I may cause a Very soft or light wind to occur that the package will not be hard or tight which is especially important where synthetic filamentary yarns are used.

The winding machine here partly illustrated is of the type well known on the market, and illustrated in patents owned by the Universal Winding Machine Company and the Foster Machine Company and others, wherein a package is formed upon a core having a conical base, with the arrangement such that there is a conical end formed on the package. In Figure 1, I have indicated the end of one such winding machine, the body of which is designated as having a stud H extending therefrom upon which is rockably mounted a frame l2, 2. counterweight designated I3 is located at one end of this frame and tends to swing the frame to a vertical position. The thread guide consisting of a porcelain disk I 4 having a notch It for insertion of the thread is carried by this frame and guides the thread as it builds up its diameter on a package. The body ill of the machine is provided with an are shaped member [6 against which a friction rod Ill pivoted as at ['8 to the frame i2 is adapted to bear 1 during the winding operation. This frame: provides one arm of the mechanism or means which form the subiect of this invention.

The package mandrel is designated generally 20 upon which there is mounted a bobbin 2| having a barrel portion 22 and a tapered or conical base 23. The mandrel is driven by a pulley from some suitable source, not shown, and rotation is controlled by. a clutch 24 which may beoperated by a handle 25 shown as extending upwardly in'Figures 1 and 2. The mandrel and "toward the 'upright'portion by suitable manipubobbin thereon are so arranged as more fully described in my prior Patent 2,099,985 as to tend to move to the right as shown in Figures 2 and 3 as the yarn is Wound thereon. In order that the endwise movement of the bobbin may be controlled, a follower roll 21 is mounted on the end of an arm 23 which is pivotally mounted as at 29 by afstud threading .into theframe Hi .50 as to swing about the axis of this stud to cause the roll 2'! to move away from the axis of the mandrel as the package builds up. This roll engages the surface of the package and its endialso engages the conical base 23. The conical base is permitted to move axially or :endwise only .in accordance with the amount'that the'rollmoves outwardly away from the axis of the package. All as more fully described in .my'a'bovesmentioned patent.

The roll 2! rotates on the axis of a shaft 30 which is mounted in a frame-like structure 3| having a base '32 which is 'slidabl'e in the guide "ways '33 formed by portions 34 *o'fthe laterally extending portion 35 of the arm of "frame 2 8. A

"bracket 36 is secured to the end-of the lateral portion 35 and carries a screw '37 having a threadedend 38 whielrhas threaded engagement 'with the frame '32, while "a spring 39 tends to "move the frame away from the upright portion 40 of the bracket, or the same may be drawn lation of the screw '31. Thus, the "position of 'this'roll 2 withreference to the arm ztzmay be nicely adjusted. Aporti'onof a gear All is mountedon'the pivotal :axis 2!! of the arm 28, and-is'fixed to this'arm-so r *as to move therewith by reason of there *being fixedto the gear an extension 42 whichlies along the arm 28 and is secured in ad'justed'position about the axis '25 by reason of a slot 83 inthis portion :and a threaded pin 4% extending through "the slot and into the arm 28,'so as tohold this gear in 'adjustedposition relative to the farm, and in order to assist in the adjustment ofthis gear, relative to the arm, 'a screw 46 extends *through a boss in the portion '42 and 'bears i against the arm 28 with aspring encircling this screw, so that by turning the screw 'in 'a right- *hand direction, the gear will be rotated about the pivot with reference to the arm clockwise, which will be assisted by the spring; Whereas, :if the screw is'turned in the opposite direction, the

spring will force :the arm so asto turn the gear counter-clockwise withreference to the arm 28. The gear meshes with a gear 48 which is ="fixed to thearm l2 by-means of 'aushape bracket 49 with which it maybe cast integrally andhaving end portions 50 and 51 secured :by means of screws 52 and53 to the arm ii. The U shaped bracket is such as "to stradd e the knob-55 which is "a customary part of the machine.

From the above, it will be readily apparent that I may'substitute "an arm carrying the follower roller with a gear thereon for the 'one usually used, such as shownfin my above-mentioned patent, and provide :a bracket with a gear to ?be secured to the arm "carrying the traverse guide, and that by this arrangement :and *the Swinging of the gear i about its yp'ivolt 29 by reason'o'f the screw "46 I may cause the follower roll '2'! "to engage the surface of ithepackage 5H fin Figure '5, *while by reason of the gear room finecti'on of this arm 28' to the arm l-2,-I:.may-;cause the porcela n thread traverse guide F4 to l'b'e 'gspace'd from the surface of'the package, cas slrown -'in" Figure-*5. Thus, "as-the package buildsnpythe' arm 28 will swing about its pivot 29 to the left, as shown in Figure 1, and through the gears will correspondingly move in unison the spaced thread guide away from the axis of the package on the other side thereof, thus insuring all of the time that as the thread is being delivered to the package, the traverse guide will be spaced from the gpackage and ;a loose or soft wind of thread in package "form will result. I may control the ,compactness of wind of the package by merely adjusting the screw 46 so as to permit the traverse guide to :be positioned closer to or further from the axis or surface of the package as it is wound, Whihtis extremely important where synthetic yarns 'suc'hiasmylon and the like are used.
